Abstract

BACKGROUND: The use of acetylcholinesterase (AChE) insecticides is still widely used by farmers in flower and agricultural centers. However, biological monitoring of farmers is still very rare in Indonesia. AChE inhibitors are reported to have toxic effects on various organs.METHODS: This study involved 120 subjects in Cihideung, Cikole and Pangalengan areas. All subjects have been interviewed, physically examined and biological sample taken by medical team. Descriptive analysis was performed to assess general conditions of the subjects and AChE erythrocyte activity enzyme at pseudo-baseline and the next 3 months from pseudo-baseline. Statistical analysis have been performed of the pseudo-baseline AChE erythrocyte activity with hypertension and history of exposures.RESULTS: The median value of pseudo-baseline AChE erythrocyte activity was 8.10 (1.3-14.25) U/g hematocrit. In the comparison between pseudo-baseline and 3 month from pseudo-baseline AChE activity, 7 respondents from 19 respondents (36.84%) had lower enzyme activity than 70% and the others subjects have higher activity value. AChE erythrocyte activity is associate with frequency of insecticide exposures. AChE erythrocyte activity (p=0.04; Exp (B)=2.937 CI 95%=1.049-8.224) and age (p=0.025; Exp (B)=3.872 CI 95%=1.180-12.703) are independent risk factors for hypertension in farmworker.CONCLUSION: AChE erythrocyte activity associated with frequency of insecticide exposures and hypertension among farmworkers.KEYWORDS: AChE erythrocyte activity, frequency of insecticide expsoures, hypertension

Abstract

BACKGROUND: Croton caudatus Geiseler (CCG), a local herb that empirically has been used as traditional medicine for malaria, fever, convulsions, and rheumatic arthritis. This study aimed to investigate the effect of CCG on reproductive and biochemical parameters in male Wistar rats.METHODS: Twenty-four Wistar male rats were divided randomly into four groups, which were treated with CCG aqueous root extract at the concentration of 0-16 mg/kg, via oral gavage. After 21 days of treatment, blood, sperm, and testes were harvested for analyses. Sperm parameters were evaluated using computer-assisted sperm analyser (Hamilton Thorne Sperm Analyzer), and morphometric analyses of histological changes were performed.RESULTS: CCG extract at 8 and 16 mg/kg significantly (p<0.05) increased the total sperm count, concentration, and motility; whereby, only 16 mg/kg significantly decreased the percentage of abnormal sperm morphology. Testosterone hormones levels were the highest in 4 mg/kg CCG but were slightly decreased in 8 and 16 mg/kg CCG. The histological results showed a significant increase in the germinal epithelial height, decrease of lumen size at 16 mg/kg of CCG extract. No significant changes of alanine aminotransferase (ALT) and creatinine levels in serum from all CCG extract groups. However, the aspartate aminotransferase (AST) level in 8 mg/kg CCG was elevated, and the blood urea nitrogen (BUN) level was decreased in all CCG extract groups.CONCLUSION: In conclusion, the CCG extract at 4 mg/kg has the potential to enhance spermatogenesis activity within the seminiferous tubules in rats without any hepatotoxicity and nephrotoxicity effect on the liver and kidney.KEYWORDS: Croton caudatus Geiseler, rats, spermatogenesis, seminiferous tubules, testis, testosterone

Abstract

BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease with dysregulation of somatic hypermutation (SHM) and class switch recombination (CSR) have been known to contribute for its lymphomagenesis. Activation-induced cytidine deaminase (AID) enzyme plays a vital role for both processes. Multiple myeloma oncogene 1 (MUM1) is known to upregulate the AID expression in normal and pathological conditions. However, both AID and MUM1 expression association in DLBCL is still unexplored using immunohistochemistry method. We examined DLBCL samples and then retrospectively tested its correlation with clinical findings.METHODS: A retrospective cohort study with 20 cases of DLBCL biopsy tissue with AID and MUM1 antibody was conducted. The samples were then classified into concordant (AID+/MUM1+ or AID-/MUM1-) and discordant group (AID-/MUM1+). The clinicopathological comparison was performed to observe any association between immunohistochemistry expression and clinical findings.RESULTS: Among 20 samples of DLBCL, concordant expression rate of AID and MUM1 was 80% with kappa Cohen’s of 0.578 (p=0.004). A significant association was observed between AID and MUM1 expression with a prevalence ratio of 2.25 (95% CI: 1.08-4.67; p=0.008). Clinical characteristics were not significantly different between each group. Restricted mean survival time was shorter in the concordant group compared with the discordant group but statistically insignificant (21.16 vs. 22.5 months; p=0.531).CONCLUSION: The result of this study showed the association between AID and MUM1 expression in DLBCL. However, whether the association may add further molecular heterogeneity of DLBCL is still to be confirmed by expanding the study.KEYWORDS: AID, CSR, DLBCL, MUM1, SHM

Abstract

BACKGROUND: Cholecalciferol, hepcidin, and soluble transferrin receptor (sTfR) interaction play an essential role in iron hemostasis. Anemia in pregnancy contributes to morbidity and mortality both for the mother and baby. In this study, we assessed the correlation between hepcidin, sTfR and cholecalciferol in third trimester maternal anemia. We aimed to find the cut-off for hepcidin and sTfR.METHODS: A case-control study involving 56 pregnant women in each anemia and healthy group was nested on a previous larger cohort study in Indonesia. Serum hepcidin, sTfR and cholecalciferol level were measured by enzyme-linked immunosorbent assay (ELISA) method.RESULTS: Serum hepcidin and sTfR level were significantly higher in case group, while serum cholecalciferol level has no difference between the two groups. New cut-off points were found for hepcidin (<15.93 ng/mL) and sTfR level (>2234.45 ng/mL). Low level of hepcidin (OR=5.32) and high level of sTfR (OR=8.28) increase the risk of anemia. High level of sTfR (adjusted OR=4.725; CI 95%=1.730-12.904; p=0.02) was the most important factor contributes to anemia, followed by the low level of hepcidin (adjusted OR=3.677; CI 95%=1.363-9917; p=0.01).CONCLUSION: The high level of sTfR is the most important factor related to anemia in the third trimester, followed by the low level of hepcidin. Low cholecalciferol level tends to favor the incident of anemia. The new cut-off point of third trimester sTfR and third trimester hepcidin were established in this study and may be useful for risk assessment and treatment monitoring for anemia in pregnancy.KEYWORDS: anemia, cholecalciferol, hepcidin, pregnancy, soluble transferrin receptor

Abstract

BACKGROUND: Hormesis was initially defined as a phenomenon where a small dose of harmful agent exposure to living organisms gives beneficial effects. The dose and time of this ‘tress’ exposure has become the object of investigation across the broad range of biomedical studies.CONTENT: Hormesis characterized by the biphasic dose-effect or time-effect relationship for any substance. Some hormetic mechanisms performed biological plasticity, involve oxidative damage which instead induce antioxidant enzyme production in various cells. Early-life stress can increase resilience in later life and lack of stress can lead to vulnerability. Many stressors like dietary factors and natural environmental toxins can be occupied for healthy growth or homeostasis, which exemplifies how illness is the doorway to health.SUMMARY: Hormesis reconcile many paradoxical phenomena exert opposite effects of the same substance, either a xenobiotic or an endogenous substance, a hormone or a metabolite, a genetic manipulation or an epigenetic alteration, an experimental intervention or a natural event. Human bodies are highly adaptive. A resilient body would be resulted after the ‘training’. In this review, we will elucidate the hormesis’ definition, mechanisms and pathways, and also how hormesis impacts in human health and lifespan.KEYWORDS: biphasic, cell signaling, dose response, hormesis, preconditioning

Abstract

BACKGROUND: Lead (Pb) was known as one of systemic toxic agent. In the body, lead may be deactivated by the metallothioneins. Paddy leaves contain metallothioneins, sugars and pythosterols, and studies have shown the pharmacological activity of rice leaves on the protective effect of lead-induced rats against kidney function. The aim of this study was to evaluate the role of IR Bagendit paddy leaves extract as hepatoprotective agent.METHODS: Twenty-eight rats were divided into four groups: one control and three treatment groups. Control and treatment groups were exposed to lead of 0.5 g/kg body weight (BW)/day and then the treatment groups were administered with paddy leaves extract of 0.2; 0.4; and 0.8 g/kg BW/day per oral for 8 weeks. On the last day of the 8th week, body weight was measured and the numbers of normal, degenerative and necrotic liver cells were examined with hematoxylin-eosin staining. Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) were measured as liver function parameter. Difference of variables between control and treatment groups were examined by Friedman test.RESULTS: There was no association in different BW between groups. The normal liver cells are higher in treatment than control group (p<0.001) and necrotic liver cells are lower in treatment than control group (p≤0.001). There was no association in degenerative liver cells between groups (p=0.153). The activity of transaminase enzymes are lower in treatment than control group (p<0.001).CONCLUSION: IR Bagendit Paddy leaves extract reveals hepatoprotective activity by improving liver cells morphology and reducing the activity of transaminase enzymes after lead exposure.KEYWORDS: paddy leaves extract, liver normal cell, necrotic cell, transaminase enzymes

Abstract

BACKGROUND: Recently, coffee is widely used for preventing photoaging because of its antioxidant capacity. Among two kinds of coffee, robusta coffee has higher content of antioxidant such as chlorogenic acid (CGA) and caffeine. Researchs about robusta coffee bean effect on photoaging due to UVB radiation is still limited. Therefore, the aim of this study was to examine the effect of robusta extract cream (RE cream) on preventing wrinkle in mice induced by ultraviolet-B (UVB) radiation.METHODS: RE cream was made by mixing RE coffee with moisturizing cream in different concentration (10%, 20%, and 40%). Twenty-five male of Mus musculus Balb/c strain mice aged 4 weeks were divided into five groups; control group, UVB group, UVB + 10% RE group, UVB + 20% RE group, and UVB + 40% RE group. The UVB groups were given UVB radiation three times a week with an exposure duration of 100 seconds per time for ten weeks. At the end of the treatment, skin samples were excised and statined histologically, also were analyzed for their protein expression. Evaluation of wrinkles was carried out using the Bissete method before and after treatment. To evaluate the thickness of the epidermis, HE staining was performed, while masson Trichome staining was performed to determine the collagen content.RESULTS: RE cream-treated groups showed lower wrinkle score compared to the control group. Furthermore, in UVB + 10% RE group, the RE cream application reduce wrinkle formation. In UVB + 10% RE group and UVB + 20% RE group, the RE cream application increased epidermal thickness and collagen content (p=0.00). While collagenase, matrix metalloproteinase-1 (MMP-1) expression was lower in UVB + 20% RE group compared to the UVB group (p<0.05), however the MMP1 expression in UVB + 40% RE group was higher than other treatment group.CONCLUSION: RE cream prevents wrinkle by maintaining epidermal thickness and collagen contain. RE cream also decreases MMP-1 expression in mice.KEYWORDS: coffee, collagen, MMP-1, robusta, wrinkle

Abstract

BACKGROUND: There is a continuous rise in the prevalence of central obesity and become a pressing health problem in the world. Central obesity followed by many metabolic disorders especially Type 2 Diabetes Mellitus (T2DM). The pathogenesis started from overnutrition signal that force pancreatic beta cells to produce a large number of insulin. Low-grade chronic inflammation that occurred also affects the organs sensitivity against insulin and caused beta cells to compensated this situation and at the end become exhausted and loss its function.CONTENT: Along compensation mechanism, certain nutrients were support the beta cells to maintain their mass and function to produce insulin. Short chain fatty acids (SCFAs) are gut microbiota fermentation product that act as nutrient and give an advantage to the proliferation and survivability of the beta cells. Zinc (Zn) also plays an important role in every step of insulin production. Moreover, these nutrients protecting pancreas against inflammation and oxidative stress through certain mechanism. Most of patients with central obesity are unaware of the presence of this disturbance at early stage. Whereas, at molecular level there is a magnitude of SCFAs and Zn level in the blood that would become an early signal and predict the damage of beta cells.SUMMARY: Quantification of these two nutrients in the blood expected to provide an early warning tool to maintain insulin adequacy and predict the possibility of beta cell failure in central obesity with promising performance.KEYWORDS: central obesity, T2DM, SCFAs, Zinc, beta cell failure

Abstract

BACKGROUND: Cancer-associated fibroblast (CAF) is the most abundant tumor stroma. Our previous study has demonstrated that the secretomes of CAF isolated from colorectal carcinoma (CRC) patients could induce epithelial-mesenchymal transition in the HT-29 CRC cell line. However, the role of CAF secretomes in CRC stemness is needed to be further investigated. Therefore, the present study aimed to investigate the effect of CAF secretomes from CRC patients on the expression of stemness markers in HT-29 CRC cells in comparison with the secretomes from normal fibroblasts.METHODS: Fibroblasts were isolated from tumor (CAF) and their counterpart non-tumor (NF) areas of three CRC patients undergone surgical resection. Normal preputium fibroblasts (PF) were isolated during circumcision of three healthy boys aged 8 years. All fibroblasts were grown in free-serum culture medium for 24 hours to collect 50% (v/v) conditioned medium (CM). Then, CM was supplemented to HT-29 CRC cells for 72 hours. The effects of CAF- and NF-CM on the mRNA expression of CD44, CD133, OCT4, and ALDH1A1 were analysed using qRT-PCR. Cells proliferation was measured using the trypan blue exclusion assay.RESULTS: Supplementation of CAF-CM (50% v/v) significantly increased CD44, CD133, OCT4, and ALDH1A1 mRNA expressions compared to that of NF-CM and control without supplementation but had no effect on the proliferation of HT-29 cells.CONCLUSION: CAF secretomes from CRC patients upregulate the expression of CRC stemness.KEYWORDS: cancer-associated fibroblasts, ALDH1A1, OCT4, CD44, CD133, colorectal carcinoma

Abstract

BACKGROUND: Iron-overload cardiomyopathy (IOC) is a major comorbidity in patients with chronic repetitive blood transfusion due to myocardial iron uptake that facilitated by calcium channels. As cardiac compensatory mechanism to IOC, we hypothesized the cardiac calcium channels expression would be increased and involved in cardiomyopathy progressivity. This study was aimed to investigate the gene expression of calcium channels in the heart of the iron overload mice model.METHODS: Mice were divided into three groups according to iron administration doses 0, 0.1, and 0.3 mg/day. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were measured for the representation of cardiovascular outcomes. The heart tissues were harvested. Further mRNA levels of L-type calcium channels (LTCCs) and T-type calcium channels (TTCCs) were examined using semi-quantitative PCR. The expressions of cardiac calcium channels and blood pressure among the three groups were compared.RESULTS: The expressions of TTCCs in the two iron-injected groups were higher than the control group (p=0.018). The expressions of LTCCs were not different (p=0.413) among groups. SBP, DBP, and MAP of the iron-injected group were lower than the control group (p=0.025, p=0.011, and p=0.008, respectively).CONCLUSION: Iron administration affects the expression of TTCCs but not the LTCCs, accompanied by decreasing of systolic and diastolic blood pressure.KEYWORDS: cardiomyopathy, iron overload, L-type calcium channel, T-type calcium channel.
